Abstract

This study aimed to investigate the influence of personal and situational factors of agricultural extension officers on their performances. The hypothesis assumed that personal factor and situational factor affect the performance of agricultural extension officers. The subjects of this research were 130 agricultural extension officers who were civil servants of Konawe Regency, Southeast Sulawesi Province. To assess the objectivity of these officers’ performances, the research also involved as samples two farmers whom every officer targeted for the extension. Therefore, totally there were 260 farmers participating in the research. The research used a quantitative method with qualitative description. The results of analysis showed that personal factor provided a significant influence on the performances of the officers of agricultural extension as much as 25% at the significance level of α=5%, and the situational factor directly influenced the personal factor as much as 29% at the significance level of α=1%. Keywords: agricultural extension, personal factor, situational factor, performance

Abstract

Dalam penelitian yang berkelanjutan ini bertujuan untuk menemukan senyawa bioaktif alami dari tanaman Indonesia, diperoleh hasil bahwa ekstrak metanol dari biji Erythrina variegata (Leguminosae) menunjukkan aktivitas paralitik dan daun E. variegata menunjukkan aktivitas antimalaria. Ekstrak metanol dipisahkan komponen-komponennya dengan kombinasi kolom kromatografi diperoleh dua senyawa aktif (1 dan 2). Struktur kimia senyawa aktif (1 dan 2) ditetapkan berdasarkan data-data spektroskopi dan perbandingan data dari senyawa yang berhubungan dari penelitian sebelumnya, dan diidentifikasikan sebagai alkaloid eritrina (1) dan turunan triterpenoid pentasiklik (2). Senyawa (1) memperlihatkan aktivitas paralitik terhadap instar ketiga ulat sutera (Bombyx mori) dengan ED50 15 μg/g diet. Senyawa (2) memperlihatkan aktivitas antimalaria dengan IC50 0,243 μg/mL terhadap pertumbuhan P. falciparum secara in vitro. Kata kunci: Erythrina variegata, Leguminosae, aktivitas paralitik, antimalaria
